JAMES N. XV. "WILSON, OF UPPER MARLBOROUGH, MARYLAND, ASSIGNOR OF ONE-HALF TO F. SNOVDEN HILL, OF SAME PLAGE.

BAYONT ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No. 358,911, dated March 8,1887.

Application filed November 13, 1886. Serial No. 218.814. (No model.)

To all whom it may concern:

Be it known that I, JAMEs N. W. \V1LsoN, a citiaen of the United States, residing in the town of Upper Marlborough, in Prince Georges county, State of Maryland, have invented a new and useful Bayonet Attachment, of which the following is a specification.

My invention relates to improvements in the way bayonets are attached to rifle-barrels; and

fo the objects of my improvements are, first, to attach the bayonet permanently to the barrel, and, secondly, to nx and untix77 said bayonet by an attachment which allows the bayonet to half-revolve and be secured in either position by a spring and catch, the bayonet,

.when unfixed, being adjusted to the side of the barrel and its point protected by a sheath on the stock of the riiie. I attain these objects by the mechanism illustrated in the aceo companying drawings, in which*- Figure lis a front View of the attachment andbayonet when fixed and unfixed. Fig. 2 isa side view of the attachment and bayonet when fixed. Fig. 3-is the outer circular casing of the attachmentwiththebayonetconnectedthercto.

Fig. 4 is a top View of the inner circular casing of the attachment as it appears after the removal of the outer circular casing. Fig. 4*L is the main spring and catch shown in Fig. 4.

3o Fig. 4 is the extraspring intended to strength en the said main spring, also shown in Fig. 4. Fig. 5 is a sectional View of the whole attachment. Fig. 6 is a side view of the interior of the attachment as it appears after the removal of the outer circular casing.

Similar letters referto similar parts th roughout the several views.

The bayonet A (of any form desired) is pointed at one end and at the other enlarged 4o to make the outer circular casing of the attachment B, as shown in Figs. 3 and 1. It fits over the interior of the attachment C, Figs. I, 4, 5, 6, and half revolves around it, being fastened to it by a screw, D, Fig. 2, which passes through the center of the outer circular casing, E, Fig. 3, permitting it to revolve, and is fastened with threads in the bottom F of the interior of the attachment, Figs. 4 and 5.-

In the outer circular casing, B, Figs. 1, 2,

5o are two apertures, G G, the one opposite to the other, through which passes the lug or catch H of the main spring I, Figs. 4 and 5, said main spring being strengthened by au eXtra spring, K, Fig. 4. These springs are within the inner circular casing of the attachment, against the bottom therein, and the lug ofthe main spring passes through an aperture, L, in said inner circular casing, as shown in Figs. 4, 5, and 6. On said inner circular casing is a stop, M, Figs. 1, 2, 3, 4, 5, and 6, 6o which permits the bayonet to only make halfrevolutions. The bayonet and attachment are fastened to the barrel by the arms N N, Figs. 1, 5, and 6, secured by a screw, O, Figs. 1, 5, and 6.

I am aware that prior to my invention bayonets have been attached permanently to the rifle-barrels, and therefore do not claim such permanent attachment, broadly; but

Vhat I do claim as my invention, and desire 7o to secure by Letters Patent, is

l. A bayonet attachment for a lire-arm, which consists of a body for connection with the barrel, a revolving head thereto, and a bayonet carried by such head.

2. In a bayonet attachment, the combination of the arms N N, secured together at their outer extremity, so as to embrace a gun-barrel, the casing B, which receives and half revolves about the body from which such arms extend, So said casing carrying abayonet, and means for securing the attachment to the gun-barrel, as set forth.

3. In a bayonet attachment, the combination of the arms N N, secured together at their outer end, so as to embrace a gun-barrel, the casing B, which receives and half revolves about the body from which said arms extend, said casing carrying a bayonet, and a stop mechanism intermediate the casing and the 9o clamping-arm N, to limit the axial motion of the bayonet, as set forth.

4. In a bayonet attachment for a lire-arm, a clamping-yoke, N N, combined with a casing,

B, which revolves about the inner extremity or body of said clamping-yoke and carries a bayonet, A, a spring-stop carried by the yoke- IOO B, which revolves about the inner extremity and thereby assist in holding the bayonet in or body of said clamping-yoke and carries a place, said pin and Way being upon the yoke- 10 bayonet, A, :t spring-stop carried by the yokebody and easing, respectively.
